This experiment was conducted to obtain information on various characteristics of triticale cultivars collected from overseas. Ten cultivars such as PRAG46/2, PHTSP Ⅰ/Ⅱ, GABO, S50RI, R70/2, BANJO, WAPITI, SUL-IN, TC-2 and Chuchuhomil were sown in the experimental field of Ansong National University in 1995, and their agronomic traits such as growth, yield, and feed value were examined. The triticale cultivars were classified by using principal component analysis on the basis of the agronomic characters examined. The triticale cultivars except Chunchuhomil were short stature. Leaves per plant in PRAG46/2 and GABO were numerous. Fresh and dry weight per plant were the highest in S50RI, GABO, and R70/2. PHTSP Ⅰ/Ⅱ showed the highest number of grains per plant and 1,000 grain weight, and therefore the highest grain yield. GABO, WAPITI, and SUL-IN showed the high content of starch, total sugar and crude protein. In the result of principal component analysis for fifteen characters, about 70% of total variation could be appreciated by the first two principal components, the first principal component was high loaded with plant height, fresh weight per plant, dry weight per plant, yield per plant and number of grains per plant, the second principal component with crude protein, potassium, calcium and magnesium content. Four varietal groups were classified by scatter diagram based on the first and second principal component scores. The second group of the four classified groups had three sub-groups. The first group, Chunchuhomil and PHTSP Ⅰ/Ⅱ, must be useful for breeding materials because those have better agronomic characters related to growth and yield than others.
